A well-known musician of my acquaintance is severely dyslexic but, following a brief spell of remedial teaching as described by Dave, passed a Cambridge entrance exam, was awarded an Exhibition and went on to acquire a good degree. He still has difficulty reading music but learned abc instead. Mrs Route counted him among her 'boysies' (to his intense irritation) at one point but has now, thankfully, as a result of her extremely limited attention span, desisted. For this reason I won't disclose his name as he is revelling in getting back his life and reputation.
